“The issue is not the loopholes. It’s the problem that once you start looking at how easy it is to get around it, you would literally have to ban every semi-automatic rifle that’s sold,” Rubio said during a CNN town hall event after last week’s Florida school shooting.

He was then interrupted by applause.

“Fair enough, fair enough. That is a valid position to hold, but my colleagues do not support banning every semi-automatic rifle sold in America,” Rubio said, prompting jeers from the crowd.

Rubio, meanwhile, said at the event that he would support raising the minimum age requirement to purchase a rifle, something that other lawmakers have signaled support for. The National Rifle Association, however, has come out in opposition to such a change.

Rubio added that he supports banning bump stocks and improving the country’s background check system, measures that have received support from the Trump administration and other lawmakers.
